ct20b on 2nd gen, whos running this set-up? Options

[95st-celica]

i will be picking up a ct20b for my 2nd gen this weekend, and was curious as to see who else was running the same set-up, as well as what other supporting mods you have, and what kind of numbers you were getting out of it as well.

I think this will really open up and answer a lot of questions about the limits of a basically stock 2nd gen, (for us 2nd gen guys) compared to the stock 3rd gen, with such a simple upgrade as a 20b.

From what i have researched, 290-320WHP should be attainable with simple mods to the 2nd gen.

Myself and lagos are going to see what we can do with each of our set-ups, and post back what we came up with.

I really do think that 300WHP is VERY realistic for the 2nd gen with the ct20b, if not more.

Here is the goal for this project...
A lot of the data and tuning theories we have come from the mr2 guys. While they do have the same GEN2 3SGTE and GEN3 3SGTE's as we do, their horsepower numbers are generally much lower than ours. Those guys go nuts when they slap on a ct20b and their car makes 230hp, while our 2nd gen engine swaps do that and more out of the box, due to the front engine layout, slightly more aggressive ecu's and ability to run massive intercoolers vs their tiny side mounts or trunk mounts.

Over the years I have come to realize that the mr2 guys are just not as right on everything as I originally thought. The constant bashing of SAFC tuning on the stock 3sgte (im not talking about alcohol injection) is a prime example of this, as there are ways to use the tool to tune the car for far greater spool up and throttle response than stock (I've been planning on making a thread about this).

On the other hand, our Celica communities seem to be very far behind in our research and documentation. We have guys here that build 5sfTe's or upgrade their turbo, and never bother to visit a dyno, and when they do, they post some kind of crappy scan of a print out that no one car really learn from. Manny and I did our best to kind of change that by posting screenshots of our runs and getting other members to do the same...

So anyway, this will be a research project to show some data on what you can expect when you upgrade your GEN2 3SGTE to a ct20b. My goal is not to beat someones peak horsepower number for bragging rights, as anyone who has been to a dyno a few times knows is pretty much a meaningless ballpark figure and that your actual performance on the street will differ depending on many conditions. The goal will be to show that the 2nd gen can kick some ass, and that its not a worthless setup. I want to compare the power curves at the same boost levels of the 2nd and 3rd gen engines and see exactly how things like TVIS and the slightly higher compression ratio of the 2nd gen compare to the slightly more aggressive cams and bigger intake manifold of the 3rd gen.

So basically, my goal is to make the same or more power at the same boost level as the 3rd gen engine, and provide an upgrade path for all the 2nd gen owners we have in our community.

Joe already has an SAFC that we will be installing once the weather gets nicer (or we find a garage to use). He still needs to put an exhaust on his car, buy a wideband, get alcohol injection..etc... so in the mean time his turbo is going on my car. By the time he gets all of that situated I will also purchase my own ct20b and we will be running the same setup, with him using the same tune, nozzle size, boost level,etc... that we have determined from this project.

ps. just to clarify a bit more... I am not simply going to copy califcarms setup. Thats not really what this is about. We do however plan to crack 300hp.
